I have an HTML document in which the various files are distributed in a quite complex directory tree-structure, and in which most of the file references are contained in JavaScript expressions. Is there any way, short of changing all the internal (E.G. ../../d1/d2/f.jpg) file pointers and renaming most of the files, to "add" the document to Calibre?

Attached are two typical HTM files, with the extension changed to .txt, and a diagram of the whole tree structure.
